A highly thermally stable benzoxazine resin derived from norbornene and natural renewable tyramine and furfurylamine

Highly thermally stable polymeric materials synthesized from renewable resources are highly desirable in many high-performance fields due to the sustainable development of human beings. Herein, a new norbornene-containing monobenzoxazine thermosetting resin ( HPTM-fa ) exhibiting very high thermal stability has been prepared using natural bio-resourced tyramine and furfurylamine as starting materials. The structural details of HPTM-fa were characterized by FT-IR, NMR as well as high-resolution mass spectroscopies. The polymerization behaviors of cross-linkable norbornene , oxazine ring, and furan groups in HPTM-fa were investigated by DSC and in situ FT-IR analyses. In addition, the polybenzoxazine thermoset derived from this newly obtained bio-based mono-benzoxazine resin showed very high thermal stability with a T d5 of 413 °C and a glass transition temperature of 290 °C. The outstanding performance of thermoset based on HPTM-fa evidences its potential applications in the design of highly thermally stable polymeric materials.
